BAG-BUNDLING MACHINE.

Specification of Letters Patent.

Patented Sept. 8, 1914.

Application filed February 3,1911. Serial No. 666L305.

.rork, have invented a certain new and useful Bag-Bundling Machine, of which the ea'ch ball of each frame'is secured at one end following is a specification.

Our invention has for its object a particularly simple and efficient machine for bundlingflat articlesv as bags; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

- Figures 1 and 2 are, respectively, end and side elevations of one form of this machine. Fig. 3 is a sectional view illustrating the folding of the bags. Fig. 1 is an end elevation of a slightly modified form of the ma chine shown in Figs. 1 and 2.

This machine for bundling flat articles comprises, generally, opposing clamping elements for folding the side portions of such articles, and means for holding the intermediate portions thereof during the folding operation.

The clamping elements and the means for holding the intermediate portions of the articles are preferably supported on asuitable base, but obviously the base, if desired, may I I bars of the frames of the clamping elements be dispensed with. i v

In the illustrated embodiment of our invention 1 is the base having a table 2 on which vthe articles to be bundled are placed 1 one upon the other, as indicated in Fig; 3. f3 1 arethe opposing clamping elements pivoted i to the base and each usually comprising a frame including end bars 4 and allengthwise bar connecting the end bars and extending parallel to the pivotalv axes of the clamping elements, each clamping element also comprising parts as 5 spaced apart in a direction'lengthwise of the frame andextending in a direction parallel to the end bars, said parts being'secured to the length.- wise bars.

The end bars arepivoted at 6 to metallic reinforcing plates 7 fixed to theends of the base, and the pivots 6 of one frame ar'epreferably spaced apart from the pivots of the other frame so that the clamping elements move about different axes. However, if desired the axes of both clamping elements maybe coincident. 'Preferably. these parts I i 5 are bails constructed to permit the side portions of the bags or other articles to bulge duringhthefoldingoperation and as here shown these parts '5 are substantially. semrcylindrical or how shape in form and to the lengthwise bar'ofthe frame and is pivoted at itsother end to a rod 8 located nearthe pivot points of the clamping elements and extending beneath the table and secured at its ends in the plates 7, this red being common to the bails of both clamping aws. During the movement of the clamping elements 3, the bails 5 move in slots 9 formed in the table 2 so that the articles can be placed flat on the table prior to the foldmg operation. I p

The clampingelements 3 may, as seen in Fig. 4:, be provided with handles 10 rigid therewith but as such handles are in the way when tying the bundles of bags We preferably use operating members or handles 11, as seen in Figs. 1 and 2 which are detachable from the clamping elements and are slid.- ably engaged with the clamping elements during the clamping operation. I

,The handles 11 shown in Figs. 1 and consists merely of frames, each of which includes end bars 12 pivoted at 13 to the plates 7 and a lengthwise bar, the end bars slidably engagingthe ends of the lengthwise 3. The clamping elements 3 are held in closed position by latches 14: carried by one of said elements at opposite ends thereof andjhooking over-shoulders loprovided on the opposite ends of the otherclamping element, the latch having a plurality of notches '16 for engaging such shoulders. When the handles are rigid with the clamping elements, as seen in Fig. 4, the latch, as the latch 17 is carried by one of the handles 10. The means for holding the intermediate portions of thearticles or bags during the closing movement of: the clamping elements 3 as here shown preferably comprises a rod 18 arranged abovethe table 2 and means for holding the rod, different distances above the table, said means consisting of standards ,19 projecting upwardly from the plates 7 and each having a'verticalqseriesof notches 20 for receiving the rod 18.

Obviously the rod holds the intermediate portions of the-bags during the closing op- I eration of the jaws and when the jaws are closed and the bags have been tied up, the

rod can be removed by an endwise movebe returned to the manufacturer, as a large number of bags can be foldedthereby into a comparatively small bundle.
